Sure.  The idea to support usb forwarding over vnc comes up now and 
then.  Also having a standalone app is probably useful for testing and 
development and maybe logging the communication between guest OS and device.

Yes, I think we certainly want to do that.  I think on the qemu side we 
want plumbing into chardev and spice, maybe also vnc.  On the client 
side a library (building on top of libusb?), a standalone app and 
support in spice client and maybe gtk-vnc would be good I think.

cheers,
